Traveling back to the Unknown Regions to unravel the mystery, the Skywalkers and Solos discover an evil far more familiar than they ever expected . . . and even more terrifying.

To find out, Luke, Mara, Han, and Leia must embark on a perilous journey into the uncharted void between right and wrong. The ferocious Unknown Terrors are only the beginning of the awesome challenges that lie ahead in their quest to fathom the unfathomable.
